Well, was interesting. I have not even tried to use any caps after 338’s other than 3875’s local caps. Unfortunately, I don’t have these regs working at the moment so can not check it.

Does it get better than that? Heh, yes I’d say. While I can concur with that the simpler non-f/b supply from my page showing regulated GC supplies sounds rather different than better than LM338 (though I am honestly leaning toward it), that second non-f/b supply is better.

Listening to good music 'till 2 AM...
A good test for transient speed, harmonics, treble detail, dynamics is two vinyl LPs I have from Keith Jarrett (they are called "Volume 1" and "Volume 2").
Very good ECM pressings, as always.
This amp is impressive to say the least.

Even with a much weaker trafo (compared to the big toroid I have on the URGC) salvaged from an old amp.
I can take the conclusion that with these chips and an unregulated PSU you always have a compromise: between 1,000uf and 1,500uf capacitance is the ideal on a sonic point of view (I made tests), but of course it's always a compromize.

With a regulated PSU you can have much more capacitance BEFORE the regs, and it pays off.

How would you compare reg PS to batteries?
